Answer:
b. m = 2, b = 4
Step-by-step explanation:
y = mx + b
m = slope and b = y-intercept
The slope is 2 cause it's going up 2 squares while only going to the right one square each time, so u could right 2/1 but it's not necessary so just 2. And the intercept is 4 because that's where the line intercepts the y-axis.

Work shown below!
Step-by-step explanation:
d = 7, e = 9, f = 10
4. 29 - d = 29 - 7 = 22
5. 41 + e = 41 + 9 = 50
6. 16f = 16(10) = 160
g = 24, h = 5.5, j = 2.5
7. h + j = 5.5 + 2.5 = 8
8. h - j = 5.5 - 2.5 = 3
9. [tex]\frac{g}{h-j} =\frac{24}{5.5-2.5} =\frac{24}{3}=8[/tex]
k = 24, m = 5.5, n = 2.5
10. km = (24)(5.5) = 132
11. 3n = 3(2.5) = 7.5
12. [tex]\frac{k}{3}=\frac{24}{3}=8[/tex]
p = 24, q = 5.5, r = 2.5
13. p + 23 = 24 + 23 = 47
14. r - 1.8 = 2.5 - 1.8 = 0.7
15. [tex]\frac{pq}{r}=\frac{24*5.5}{2.5} =\frac{132}{2.5}=52.8[/tex]
A contestant on the biggest loser lost 78.8 pounds over a period of two months. At the end of the two month period, the contestant weighed 194.3 pounds. How much did the contestant weigh when the show began?
Answers
Answer: The contestant weighed 73.1 pounds when the show began.
Step-by-step explanation:
Given: A contestant lost 78.8 pounds over a period of two months.
At the end of the two month period, he weighed 194.3 pounds.
Initial weight = weight at the end of the two month period + weight lost by contestant
= 194.3 +78.8 pounds
= 273.1 pounds
Hence, the contestant weighed 73.1 pounds when the show began.
what is the solution to the system of equations?
Answers
Answer:
No solution
Step-by-step explanation:
[tex]-3x-4y-3z=-7\\2x-6y+2z=3\\5x-2y+5z=9\\\\[/tex]
Lets consider the equation 2.
Here we multiply the LHS and RHS with (-1).
[tex]-3x-4y-3z=-7\\-(2x-6y+2z)=-3\\5x-2y+5z=9\\\\[/tex]
Hence,
[tex]-3x-4y-3z=-7\\-2x+6y-2z=-3\\5x-2y+5z=9\\\\[/tex]
When we add the equations we get,
[tex]0x+0y+0z=-10+9\\Hence,\\0=-1[/tex]

A. About 405 miles
B. About 406 miles
C. About 407 miles
D. About 408 miles
Answers
Answer:
the answer is be B 406 miles
Answer: B)
Step-by-step explanation: because
d= miles
t= hours
the car travels 58 miles per hour which gives us d=58t
Now it asks what is the best estimate the car travels within 7 hours so you would multiple 58x7=406

n years at the company. The table below has select values showing the linear relationship between n and S. Determine how many years Claire would have to work at the company before her salary would reach $77000.
Answers
Answer:
6 years
Step-by-step explanation:
First, you need to write an equation for this problem. I'll write it in slope intercept:
y = mx + b
where m is the slope and b is the y-intercept
To find m, do (change in y/change in x):
using (2, 59000) and (5, 72500),
(72500 - 59000) / (5 - 2)
= 13500 / 3
= 4500
So we have y = 4500x + b
To find b, plug in one of the points into the equation with the slope:
using (2, 59000),
y = 4500x + b
59000 = 4500(2) + b
59000 = 9000 + b
50000 = b
So now you have an equation: y = 4500x + 50000. Now that there is an equation, just insert the given y-value and solve:
when y = 77000
y = 4500n + 50000
= 77000 = 4500x + 50000
= 27000 = 4500x
= 6 = x
So, when Claire's Salary is 77000, her number of years at the company is 6.

You have been contracted to replace a countertop in a kitchen. You will get paid $1,000 to do the job. You can complete the job in three days working 8 hours a day. You will need to pay the cost of the materials, which is $525, with the $1,000 that you receive to do the job. How much will you be paid per hour for your time?
Answers
Answer:
$19.79 cents (rounded to the nearest cent)
Step-by-step explanation:
first subtract the amount needed for materials from your total pay
(1000 - 525 = 475)
take 475 and divide that among the hours you work.
475 / 24 = 19.7916666
round that number to the closest money value
19.79
Write an equation in slope-intercept form with the following information. Goes through the points (6, 2) and (7, 5).
Slope= _____ y-intercept=_____
Answers
Answer:
The slope is 3
y-intercept is -16
Step-by-step explanation:
Let's start by using the slope formula, [tex]m=\frac{y2-y1}{x2-x1}[/tex]
plug in the points for the relating x and y and solve,
[tex]m\frac{5-2}{7-6}[/tex] this simplifies to [tex]\frac{3}{1}[/tex] or "3"
we have our slope: 3/1 or "3"
the equation needed to find the y-intercept is y=mx+b
We will need to solve for "b" to figure out the y-intercept.
let's plug in any pair of x and y, i'll just choose (6,2)
2=3(6)+b, 2=18+b, 2-18=18-18+b, -16=b
Y-intercept is -16
